摘要： A method, system and computer program product for retrieving data records to a client computer. An identifier of a base query is received from the client computer. The base query is configured to select a set of data records from a database that the client computer has permission to access. A modifying clause is also received from the client computer. The modifying clause comprises a directive restricting the set of data records to a subset of data records. The modifying clause may optionally comprise an expression for sorting. A combined query is generated from the base query and the modifying clause. The query is configured to return the subset of data records. The combined query is further configured to sort the subset of data records based on the value of the expression if the expression is present. The combined query is executed at the database.

摘要： A method, system, and computer program product for improving the performance of distributed object systems. A remote object is replicated to the node of the distributed system from which it is accessed. The scope of the replication is a transaction. Thereafter, method invocations on the object occur locally, avoiding the performance overhead of frequent round trips to the remote persistent object store. Changes made to a replicated object by a transaction are represented using a tree structure that is internally managed by the application. When an application or application user has made modifications to a replicated object and requests to commit the modifications, a determination is first made as to whether committing the modifications will result in an unacceptable data conflict. If no unacceptable data conflict will occur, and after resolution of those conflicts that can be resolved, the modifications are committed. Nested transactions are supported, where each child transaction may commit or roll back independently.

摘要： A technique for providing a transaction management subsystem for an enterprise computing environment in which multiple concurrent and/or nested transactions may access the same Enterprise JavaBeans (EJBs) simultaneously. The transaction management subsystem provides a view for each transaction which includes an independent version of an EJB's business logic and its instance data. When an application or application user has made modifications to an EJB version and requests to commit the modifications, a determination is first made as to whether committing the modifications will result in an unacceptable data conflict with other versions of the same EJB. If no unacceptable data conflict will occur, and after resolution of those conflicts that can be resolved, the modifications are committed. The management subsystem also supports nested transactions, where each subtransaction may have an independent view of an EJB. Subtransactions may commit or roll back independently. Changes made by a transaction are represented using a tree structure that is internally managed by the application.

摘要： A many-to-many relationship management system. In an object persistence management system, a many-to-many relationship manager can include one or more related objects; a junction table storing relationships between the related objects; and, one or more corresponding links. Each link can correspond to one of the objects. Furthermore, each link can persist state information for the corresponding object in an associated object table. Finally, each link can manage the junction table responsive to changing relationships with others of the related objects. Importantly, as the present invention distributes the management of the junction table, a counter-operation management protocol can be provided which can resolve conflicts which arise in the management of the junction table in response to changing relationships among their associated objects.

摘要： The present invention comprises a Dynamic Query Interface (DQI). The DQI provides an apparatus and method for dynamically discovering the shape of data returned by a DBMS in response to a query statement. The DQI comprises a Query Schema, a Select Macro, and a Macro Expansion Module (MEM). Unlike conventional query statements, a Select Macro only requires a select-clause. The MEM builds a conventional query statement from a Select Macro using information contained in the Query Schema. The Macro Token expansion approach implemented in the MEM obviates the need for full language parsing and is thus much more suited to runtime execution than prior art solutions. Furthermore, because the MEM examines a Select Macro at runtime, the MEM has the added advantage over prior art solutions of being able to discover dynamically the shape of the requested data at runtime.
摘要翻译：本发明包括动态查询接口（DQI）。 DQI提供了一种用于动态发现DBMS响应于查询语句返回的数据形状的装置和方法。 DQI包括查询模式，选择宏和宏扩展模块（MEM）。与传统查询语句不同，Select Macro只需要一个select子句。 MEM使用Query Schema中包含的信息从Select Macro构建常规查询语句。在MEM中实现的宏令牌扩展方法避免了对全语言解析的需要，因此比现有技术的解决方案更适合于运行时执行。此外，由于MEM在运行时检查选择宏，所以MEM具有优于现有技术解决方案的优点，能够在运行时动态地发现所请求数据的形状。

摘要： Systems, methods and computer program products automatically order database transaction by an object-oriented transaction system. The objects in the completed transaction are clustered into groups of objects to be inserted into the relational database, objects to be deleted from the relational database and objects to be updated in the relational database. The objects to be inserted into the relational database are ordered according to an insert precedence of the objects into the relational database to thereby define an insert order. The objects to be deleted from the relational database are ordered according to a delete precedence of the objects from the relational database are ordered according to a delete precedence of the objects from the relational database to thereby define a delete order. The objects to be inserted into the relational database are inserted into the relational database in the insert order. Then, the objects to be updated in the relational database are updated in an arbitrary order. Finally, the objects to be deleted from the relational database are deleted from the relational database in the delete order.

摘要： A technique for creating and using a structured cache to increase the efficiency of reading persistent objects from a database. The structured cache is comprised of an object cache, an associations cache, and a data cache. Data read-ahead is used to retrieve rows from a relational database in advance of an application's need for the data. Entries are created in the data cache and association cache as the rows are processed. The data cache stores data in unstructured binary format, delaying the expense of instantiation until an object is requested by the application. At that time, data is retrieved from the data cache, an object is instantiated from the data, and an entry is created in the object cache. This approach also saves storage space that would be wasted if objects were instantiated upon retrieval, but never used. The association cache stores members of an association, organized by member key within owner key for each association. According to the preferred embodiment, maintaining cache consistency is not required, further increasing the efficiency gains that can be realized using this technique.
摘要翻译：一种用于创建和使用结构化缓存以提高从数据库读取持久对象的效率的技术。结构化缓存由对象缓存，关联高速缓存和数据高速缓存组成。数据预读用于在应用程序对数据的需求之前从关系数据库检索行。在处理行时，将在数据高速缓存和关联高速缓存中创建条目。数据高速缓存以非结构化的二进制格式存储数据，延迟实例的费用，直到应用程序请求对象。此时，从数据高速缓存中检索数据，从数据中实例化一个对象，并在对象缓存中创建一个条目。这种方法还节省了存储空间，如果对象在检索时被实例化，但从未使用，则会浪费这些空间。关联高速缓存存储关联的成员，由每个关联的所有者密钥内的成员密钥组织。根据优选实施例，不需要保持高速缓存一致性，进一步增加使用该技术可以实现的效率增益。

摘要： A collection of target Enterprise JavaBeans (EJBs) that are associated with the source EJB in a one-to-many association is obtained in response to traversing the one-to-many association of the source EJB. The collection of target EJBs is registered in a collection registry. The source EJB is passivated without passivating the collection of target EJBs, and the source EJB is later reactivated. The collection of target EJBs that are associated with the source EJB that is reactivated is fetched from the collection registry in response to traversing the one to many association of the source EJB that is reactivated. The one-to-many association between the source EJB and the collection of target EJBs may be managed by a link object that is generated by a link factory.

摘要： A method, system, and computer program product for increasing the efficiency of operations that are to be performed against an arbitrary relational database by automatically ordering the operations according to the referential integrity constraints defined for the affected tables. Because the ordering is performed programmatically, the application developer is relieved of the burden of attempting to structure the application in a manner that avoids violating the referential integrity constraints. The efficiency of modifying the database increases significantly using this technique. The ordering may be performed at a database engine. Existing applications may take advantage of this ordering technique, without requiring change to the application itself. Batch-mode write operations are possible when using this technique, thereby reducing the number of network round-trips that must be performed.
